BUTTON-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 375,004, dated December 20, 1887.

(No model.)

To aZZ whom it may concern..-

Be it known that I, JOHN G. SGHOTT, residing in Providence, Providence county, Rhode Island, have invented an Improved Button- Making Machine, of which the following is a specification.

My invention relates more particularly to that class of button-machines in whichare used a die-bed, a removable diecollar, a punch fit- IO ting and sliding within said collar, and a plunger for operating the punch.

One object of myinvention is to so improve the diecollar as to enable button-coverings of diiferent thicknesses to be applied with its aid. Another object is to improve the means for carrying and operating the reciprocating plunger,so as to obtain greater certainty of action and simplicity of parts. l

The invention consists in the combination, with the'punch and plunger of a button-machine,of an expansion-ring adapted to receive the punch and the parts of the button. This expansion -ring, by means of its expansive qualities, permits of the use of varying thicknesses of cloth in the die-collar without straining and stretching the cloth, as is the case with rigid rings or solid die-collars.

The invention also consists in the combination, with the die-bed of the machine, of a 0 movable yoke extending over the die-bed and carrying a reciprocating plunger and a lever for operating said plunger. By moving the swinging yoke outward the plunger will be carried aside, thereby giving free access to the collar and die-bed,

Other details of improvement are hereinafter more clearly pointed out.

Reference is to be had to the accompanying drawings, forming part of this specification, in

which-- Figure l is a vertical cross-section, on the line a c, Fig. 2, of a buttonmachine constructed according to my invention. Fig. 2 is a plan View of the same, showing the swinging yoke in full lines in the outward or open position. Fig. 3 is a side view of the slotted post for locking the yoke in its closed or operative position, showing also the plunger and lever. Fig. 4 is a vertical central section, on

an enlarged scale, of the die-bed, die-collar,

and punch, showing my improved expansionring in position in the die-collar, and the parts of a button within the die. Fig. 5 is a plan view of the die-collar and expansionrin g withi in the same. Fig. 6 is a front view of the 5 machine; and Fig. 7 is an enlarged sectional View through the die-bed, punch, and expansion-ring, the die'collar being removed.

A in the drawings represents the base of a button-making machine, which base forms the die-bed.

B is the removable die-collar, adapted to fit in a groove in the die-bed A, as shown, or otherwise held thereon.

b is a ring, of spring metal, which, when the die-collar is used, is placed into said die collar. The ring 6 is of somewhat less external diameter than the interior of the die-collar B, and is split vertically, as at d, so as to be expansible. The ring I) is keptin position within the die-collar B, when the latter is used, by means of a pin, e, as shown.

Secured to the base A are two uprights or posts, D and E. On the upper end of the post E is pivoted, by a vertical pin, a, a yoke, F, the free end of which is adapted to enter a horizontal slot, 9, in the upper end of the post D, and provided with a convenient handle, f. The yoke F carries a vertical tube or sleeve,

h, in which works a vertical]y-reciprocating so plunger, G. A spiral spring, 1', surrounds the plunger G and bears at one end against the top of the sleeve 71. and at the other end against a pin or projection, j, on the plunger G. The spring 1' serves to hold the plunger G normally 8 in the raised position; but other forms of spring or other means may be used for this purpose, if desired. A lever, H, is pivoted, by a horizontal pin, 8, in the swinging yoke F above the reciprocating plunger G, and is provided with a cam or projection, Z, adapted to bear upon the plunger G to operate the same.

m is a punch carrying a sleeve, n, and it is of the usual or suitable construction for cooperating with the diecollar B. The punch 5 m and its sleeve are adapted to enter the expansion-ring 11 within the diecollar B.

The parts for making a button are a metal cup, 0, a cloth cover, 19, for the same, and a collet, q. These parts 0, p, and q are of well- :00 known construction. They are shown in Fig.

4 in the position they assume when placed in the die and before the punch descends to form the button.

To make a button on this machine the yoke F is first swung outward into the position shown by full lines in Fig. 2. This removes the plunger Gfrom over the die-bed and permits free access to the same. My expansionring b is next placed in position on the diebed, and a metal cup, 0, and its cloth cover 1) placed within the ring I), so that the cloth partly overlaps said cup, as in Fig. 4..

The punch m, containing a eollet, q, in its sleeve n, is nextplaced in the ring b,as shown 7 in Fig. 4. The yoke F is now swung into the forcing the same into the die collar, completing the button in the usual manner.

By using my improved expansion ring b cloth covers, 9, varying in thickness may be used without danger of tearing orstraining the parts, as the said ring compensates for the difference in thickness of the cloths; hence I can use the same die, plunger, and ring for coverililg buttons with very thin and with very thick 0 0th.

By my improved means of carrying and operating the plunger I am enabled to readily move the same away from over the die-bed, also toquickly place the same in position. Furthermore, I obtain a direct and positive reciprocating motion of the plunger.

It is evident that the split ring I) could be used without the collar B, said ring constituting and performing all the functions of the ordinary die-collar. This is clearly shown in Fig. 7.

It is to be understood that the die-collars B,

rings 12, and punches m may be made in series nation,with the removable die-collar B, of the split expansion-ring I), carried by said collar, substantially as described.

3. In a buttonmaking machine, the combination, with the base A, of the posts D and E, the swinging yoke F, carried by one of the posts, the plunger G, and the lever H,carried by the yoke F,allarranged and operating substantially as described.

4. In abutton-making machine, the base A, posts D and E, swinging yoke F, plunger G, and lever H, for operating said plunger, in combination with the split expansion-ring b substantially as described.

5. In a button-making machine, the combination, with a die-bed, of the die-collar B and expansion-ring Z), carried by same, and of a punch adapted to fit the die-collar, a plunger for operating the punch,and a lever for operating the plunger, substantially as herein shown and described.
